Dietary effects of Algerian sodium bentonite on growth performance and biochemical parameters in broiler chickens
No full textThe present experiment was
conducted to investigate the effect of
supplementing poultry feed with graded
levels of Algerian sodium bentonite
(Na-B) on growth performance and the
development of villus height in jejunum
and some biochemical parameters during
50 days in broiler chickens. A number of
420 one-day old broiler chicks (Arbor
Acres) were obtained from a commercial
hatchery. The birds were randomly allocated
into six groups (A, B, C, D, E and F).
The treatments were 0 (control), 1%, 2%,
3%, 4% and 5% of Algerian Na-B levels.
The results obtained indicate clearly that
weight gain in the chickens fed treatments
containing 4% Na-B had greater weight
gain than the chickens fed different treatments
(0, 1%, 2%, 3% and 5% Na-B).
Feed conversion rate (FCR) was lower
birds supplemented with Na-B 4% (2.45)
than control group (3.06). Maximum feed
consumption was observed in the birds’
control (5,655.3 g), while the lowest was
noted in the chickens with diet added 4%
Na-B (5,009.5 g) (p< 0.05). The weight of
duodenum, jejunum and ileum was
decreased for the Algerian Na-B
supplemented group, compared with the
control group. The villus height was
affected by dietary treatments (1%, 2%,
3% and 5%) on days 18 and 50 (p< 0.05).
Feeding the supplemented graded levels
Na-B resulted in an increase in plasma
cholesterol, triglyceride and HDL
concentrations at 50 days of age,
compared with the control group. These
results showed clearly that the Na-B from
Algeria can improve the growth
performance in broiler chickens. Thus, dietary inclusion of Na-B had positive
effect on plasma triglyceride, cholesterol
and HDL values in broiler chickens at the
end experiment
Challenge testing of Nigella sativa fortified Cyprinus carpio fillets quality by various regular and atypical storage temperatures
No full textIncreased interest for enhancing food quality during storage, using affordable, natural solutions, lead to studies assessing Nigella sativa for its preservation properties. The present study is focused on challenge testing of Nigella sativa fortified Cyprinus carpio fillets morphological quality. The challenge testing involved accelerated tests at temperature conditions other than those anticipated in the food industry (5- 10°C), including stress temperature trial (exposure to storage temperature variations) for fresh carp fillet supplemented with 0.6% v/w Nigella sativa seed oil (NSSO). Histological evaluation of muscle structure was performed at day 3 of storage, for all samples. The carp fillets were divided into two groups: control group (C), without NSSO and test group (T), fortified with 0.6% v/w NSSO, which was further divided into 4 groups, subjected to different storage temperatures: 3°C – group T1, 5°C – group T2, 7°C – group T3 and stress temperature trial (STT) – group T4. Group C (control) was stored at 0°C throughout the monitoring period. Histological evaluation of fish muscle revealed no significant differences between sample groups after three days of storage. This study shows promising results for the possible use of Nigella sativa seed oil, as a natural solution for promoting longer shelf life and better quality for cold-stored fresh fish
Effect of compost application on the growth of Acacia Nilotica
No full textAcacia nilotica is an important agroforestry specie, which is used in both compact and linear forms. The objective of the current study was to evaluate the effect of compost on the growth performance and biomass production of A. nilotica. Completely randomized design (CRD) was used to analyze the variations among several growth morphological traits. Two parallel trials, pot trial (seedlings), field trial (saplings) were conducted simultaneously. Compost and litter mixture were applied in mentioned trials. Following
treatments were used: T0 – control; T1 - 25% of compost and 75% of nursery soil;
T2 - mixture of 50% nursery soil and 50% compost; T3 - mixture of 75% compost and 25% of nursery soil; T4 - where 100% compost was applied. Increase in plant growth was observed with the increases in the amount of compost mixture. In field trial maximum plant
height, shoot length, root length, rootshoot ratio and biomass production was observed when 100% compost level was applied, while minimum was observed without any compost appli-cation. In pot trials, the maximum plant height, rootshoot ratio and biomass production was recorded when 75% compost level was applied. Overall, Acacia performed better with 100% of compost application in field trail and 75% of compost application in
pot trial. The results of this study demonstrated the positive effects of compost on the growth of Acacia. The seedling development was improved considerably with different levels having greater percentage of organic fertilizer and it was concluded that compost
improves soil fertility and it should be used as organic fertilizer in farming and forestry practices for improving crop growth and yield

The varieties studied were: Busuioaca de Bohotin, Cabernet Sauvignon, Feteasca Alba, Feteasca Neagra, Feteasca Regala, Muscat Ottonel, Pinot Noir and Sauvignon Petit.After the research carried out, it was found that the humidity of the strings is different, depending on the variety and the date of harvest
A study concerning the quality of spices processed in a profile unit
Get PDFAlong with mankind evolution, the food needs of the population have turned to improved nutrition, which led to the use of spices to enhance the taste and flavour of dishes. Thus, the food industry is currently confronted with the problem of meeting consumer demands, and is trying to respond positively to their specific food requirements. Besides the aromatization function of the dishes, some spices have antiseptic and antioxidant properties, favouring digestion as well. In the present study, the qualitative analysis of spices used in the meat processing industry was followed and some of the spices used in a meat processing unit being also presented. A number of 30 spice samples represented by pepper, sweet paprika, granulated garlic and thyme were analysed, organoleptically, physicochemically (moisture, granulation, percentage of impurities, heavy metal residues and mycotoxins) and microbiological (NTG, Salmonella spp., E. coli, Enterobacteriaceae, yeasts and moulds). Regarding organoleptic parameters, the spices taken in the study are in accordance with the manufacturer's specifications, being in line with the legal provisions in force. Following the analysis of the physico-chemical parameters of the spices, no exceedances of standard values were observed, the products complying with the provisions imposed by current legislation. A medium moisture value of 5.03% was recorded for the grinded white pepper, and 4.1% for sweet paprika, both being within the admissible values. For six samples of sweet paprika were analysed included contaminants (Pb, Cd, Aflatoxin B, Ochratoxin A), the results being within the limits of admissibility, according to Regulations (EC) in force (Regulation EC No. 1881/2006, Regulation EC No. 165/2010, Regulation EC No. 594/2012). Regarding microbiological parameters, all analysed samples recorded values corresponding to the legal admissibility limits. As a result of the study, it has been found that a wide range of spices is used in the food industry and the programs of self-control and official control are respected and the results obtained are in line with the regulations in force
Researches of the influence of nitrate contents on main morphological traits of maize plants
No full textNitrogen is an important
element required for plant growth and
development. It is a key component in
many biological compounds that play a
major role in photosynthetic activity and
crop yield capacity. Variation in nitrogen
availability can affect plant development
and productivity in maize. One of the
ways of soil pollution through agricultural
technology is over-fertilization and, in
particular, the administration of high
doses of nitrogen fertilizers. Excess of
nitrogen fertilizers, as well as their
empirical application, have negative
effects on harvest quality. Excessive use
of fertilizers with nitrogen, produces of
ion nitric accumulation in the soil
(temporary) and in plants, which disturbs
the balance of photosynthesis, causes the
appearance of necrosis and burns on
leaves, severe intoxication and even death
by asphyxiation phenomena and cyanosis
at ruminants, children and old people. The
main aim of this study was to determine
the effect of different nitrogen levels and
different type of fertilizers on nitrates
levels in maize leaves and on
morphological traits of maize plants. Field
experiments were conducted in two
growing seasons (2017 and 2018) with
five nitrogen levels (80 kg/ha, 120 kg/ha,
160 kg/ha, 200 kg/ha and 240 kg/ha) and
two type of nitrogen fertilizers
(ammonium nitrate and urea)
The alcmaeon project: bringing humanities, the arts and medical education together
No full textThe article is a systematic reflection on the Alcmaeon European project (2018-ES01-KA203-050606), which puts forth an alternative model for integrating the history of medicine into medical education. The project is developed within a partnership between education organizations, museums and universities from Spain, Great Britain, Italy,
Greece and Romania. The project aims at shifting the focus of teaching the history of medicine from simply chronicling events to examining the process of medical development over time and studying it as a continuous inquiry by providing medical professionals with structured and harmonized online materials available in its own virtual museum and library. In addition, the arts can be used as a means to educate students of medicine in an agreeable atmosphere by means of focused interpretation and discussion with a view to developing their professionalism, selfawareness and communication skills, increasingly important assets for physicians. Bringing these disciplines together enables students to form deeper connections with patients and develop empathy and creativity. Overall, the focus group analysis highlighted that integrating the history of medicine into medical education is necessary as it gives students insights into past procedures and achievements, raises their awareness about the importance of medical and social ethics, provides lessons in medical education, empathy, charity work, community involvement, ethical standards, and laboratory research
